Here we see the main board with several knobs and switches still attached.

This is the underside of the board. Enjoy this photoset, because getting your hands on a TR-303 is nearly impossible. Still, that doesn’t mean you have to live a 303-free existence. Check out [Ladyada]’s TR-303 clone, the x0xb0x. You can purchase the DIY board from the site and get your synth-on now.

I have a 303 which needs some work (power short of some kind…) but I’m afraid to take it to a local electronics repair place and can’t seem to locate anyone in the US who specializes in vintage synth repair. Pleaes mail me at wrothermel@hotmail.com with any tips…thanks in advance
